CERN Accelerating science

A few months are left before the start of Run 3 at CERN. With the timely completion of all upgrades planned for Long Shutdown 2 (LS2), in the last weeks the CMS detector has been set in its closed configuration.

The challenge of Run3: CMS is preparing to resume its operations for the Run-3 of the Large Hadron Collider (LHC) after a 3-year long shutdown called LS2 (2019-2021).

The CMS collaboration is happy to congratulate its members Dr. Austin Ball and Professor Phil Butler who not only made significant contributions to science but are also highly honoured in their respective countries for their achievements. 

The installation of a new prototype of  CMS muon chambers was completed last December. With these installations, the CMS detector is taking further steps towards the HL-LHC era at CERN. 

The word lepton comes from the Greek λεπτός (leptós,) meaning “small”;  the electrically charged leptons (electrons, muons, and taus) have much smaller masses than their counterparts in the quark sector.

Before saying goodbye to 2021, we’re proud to look back at major milestones reached by CMS collaboration both on physics results and detector upgrades along the year.

Since the Higgs boson discovery in 2012 by the CMS and the ATLAS col

The collision of high-energy protons at the LHC breaks them apart and allows us to look at its constituents. Surely there are more interesting stuff in store, compared to the usual constituents at lower energy, the up and the down type quarks.

As the experiments at the Large Hadron Collider (LHC) brace for the start of Run 3 of the accelerator’s programme in 2022, the CMS collaboration has released a new batch of research-quality open data recorded by the CMS detector in 2015, the first year of Run 2.
